That totally exists now. They're called Batch Actions :]

Kind of. It will sort by the ids of the parent model, instead of something more useful (like alphabetical sorting).

Perhaps because you're not using the add function? The below format works fine for me.

validate :name_must_be_cool

def name_must_be_cool
  errors.add(:name, 'Try again!') unless is_cool?(name)
end

The command rails g active_admin:resource product doesn't actually create a model; it just creates the app/admin/products.rb file so Active Admin renders a GUI for this resource when you start your server. You've got to run rails g model product first.

Assigning before_create (etc) callbacks in your model work just fine with ActiveAdmin. What exactly is your problem?
